NCT ID NCT04111627
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether adding the antidepressant duloxetine to a walking program helps older adults with both knee osteoarthritis and depression. All 43 participants received the same combination treatment. The goal was to see if the approach is feasible and if it reduces pain and depressive symptoms.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- duloxetine
- What this could lead to
- If successful, this combined approach could offer a better way to manage both knee pain and depression in older adults without surgery.
- What could go wrong
- This is a small, early feasibility study with only 43 participants, so results may not apply widely. Duloxetine can cause side effects like nausea or dizziness.
